Abstract

Procedimiento para retirar compuesto de nitrógeno de las aguas residuales, que se obtiene en instalaciones para la producción de acrilonitrilo por oxidación en fase gaseosa de propileno y amoniaco con oxígeno, caracterizado porque el agua residual se trata con reducidas cantidades de hidróxido sódico y peróxido de hidrógeno.
